'- Application filed April 19, 1920. Serial No. 374,951.

To all whom it may concern: Be it known that I, JOSEPH B NEIL, a c1t1- zen of the United States, residing at York,

in the county of York and State of Soutlha picking roll and a 5 Carolina, have invented a new and useful Cotton Picker, of which the following 1s a specification.

This invention relates to machines for .picking cotton. L a

One of the objects of the lnventlon 1s "to simplify and otherwise improve upon the structure by eliminating a good. bit of the driving mechanism heretofore necessary, thereby materially reducmg the weight of 'the machine; by dispensing with dofling brushes and using in lieu thereof suction for the urpose of stripping cotton from the picking elements; y bod1ly mov1ng ;the groups of pickin unlts to obtain the desired brushing or com ing 80111011 upon the plants during the picking operation; and by reducing the power required to operate the complete machine.

With the foregoing and other ob ects 1n 5 view, which will appear as the descrlption proceeds, the invention resides 1n thecombination and arrangement of parts and 1n the details of construction hereinafter described and claimed, it being understood that, within the scope of what is claimed, changes in the precise embodiment of the invention shown can be made without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings Figure 1 is a side elevation of the machine.

Figure 11 is a transverse section through the rolls shown in Figure 10.

Referring to the figures by characters of reference 1 desi ates a supporting structure carriedrby whee s 2 and 3, this structure beng propelled and guided by mechanism such as disclosed in my application hereinbefore mentioned and which constitutes no part of the present invention.

Sigspended within the structure 1 by means of r s 4 having screw threaded connecting bolts 5 are frames 6 adapted to travel along opposite sides of a row of plants. these frames being adjustable not only vertically by means of the bolts?) but being also shift- 7 able laterally toward and from each other, there being springs 7 connecting the structure 1 to the upper portions of the frames 6 and foot operated levers 8 for adjusting the frames.

Each of the frames 6 has a suction hood 9 covering the outer side thereof and the walls of which converge to an upwardly extending flue 1c. The upper ends of the flues are in turned and are connected by flexible tubes 11 to a box 12 in communication with the air intake of a blower casing 13. This blower casing discharges into a receptacle 14 carried by the structure 1.

Mounted within each of the frames 6 near the ends thereof are vertically disposed guide rods 15 and slidably mounted on these rods from the ends of a slidable frame 17 he spaces between the upper and lower ends of the frame 17 and the corresponding portions of the frames 16 are closed by flexible strips 18 of fabric or the like so that leakage of air into the hoods 9 through these spaces is prevented.

The inner side of each of the frames 17 is provided with a series of V-shaped partition 4 upper and lower throats 20.

The outer sides of the V-shaped strips 19 form lon itudinal pockets into which the brane es of the plants bein acted on are free to expand or extend during the picking operation.

Each of the rolls 21 and 22 has its shaft 26 extended forwardly beyond the frame 17 and provided with a sprocket 27. Idler sprockets 28 are mounted on the frames 17 and a continuous drive chain 29 extends in en agement with the sprockets 27 and the idl ir sprockets 28 (see Figure 6) and also engages supplemental guide sprockets 30 mounted on the frame 17 near the top and bottom thereof. The-shaft of the upper picking roll carried by each frame 17 is connected by a universal joint 31, to a telescopic shaft section 32 which, 'in turn, is connected by a universal joint 33 to a short shaft 34 mounted in bearings carried by the frame 6. A sprocket 35 is secured to the a shaft 34 and receives motion through a chain 36 from a sprocket 37 secured to the front section 38 of a jointed transmission shaft. The intermediate section of this transmission shaft has been indicated at 39 and is connected to the shaft 38 by a universal joint 40. This intermediate section is in turn connected by a universal joint 41 to the rear section 42 of the transmission shaft and which section is journaled on the rear portion of the structure 1.

Obviously two transmimion shafts are employed, one being provided for each of the frames 6 and the mechanism driven thereby. The rear sect-ions 42 of these two transmission shafts are provided with sprocket-s 43 receiving motion through chains 44 from sprockets 45 secured to the rear end portion of an engine shaft 46. This engine shaft extends longitudinally of the structure 1 from the-motor 47. A .pulley 48 is secured vto the engine shaft and drives a belt 49 which transmits motion to a small pulley 50 secured to the shaft 51of the suction fan 52 mounted in the housing 13.

Secured to the shaft 46 is a pulley 53. A belt 54 transmits motion from this pulley to a pulley 55 secured to a. transverse shaft 56 journaled in bearings 57 carried by the structure 1. See Figure 7. Shaft 56 has telescopic sections 58 connected thereto by universal joints and lso connected to worm shafts 59 'ournaled in suitable bearings carried by the frames 6. Arranged longitudinally above each frame 6 and mounted in the bearings 60 is a shaft 61 havin a worm gear 62 adapted to be rotated b t e worm 63 on the shaft section 59. Shat 61 is provided, at each end, with a crank 64 connected, by a pitman 65, to an arm 66 extending upwardly from the slidable frame 17 thereunder. v

It will be apparent thatwhen the machine is in operation it will straddle the row of plants being operated on and will move therealong. Motion will be transmitted to the picking rolls and to the spiral rolls from shafts 38 through the chains 36 and sprockets 35 and 37 and through the chains 29 and the sprockets 27, 28 and 30. The shafts 38, in turn, will be driven by the sections 39 and 42 receiving motion through the chains 44 and sprockets 43 and 45 from the engine shaft 46. As the machine moves along the row the picking rolls will engage the cotton and carry it upwardly to the throats 20 where it will be sucked fr m the rolls into the hoods 9 and 10 and ultimately discharged into the receiver 14. If the icking rolls are made of perforated cylinders, the flow of air through the rolls will be sufiicient to cause the cotton to adhere to the said rolls until the cot-ton is brought to i the throats 20 whereupon it will be'stripped from the rolls. The s iral rolls 22 operate to keep the branches 0 the plants in proper position during the forward movement of the machine and to exert pulls upon the twigs and branches while the cotton is being gripped by the picking rolls. The pockets 25 allow the branches and twigs to expand thereinto, thus to allow the picking rolls to get close up to the stalks of the plants. As the machine advances the frames 17 will be bodily reciprocated upwardly and downwardly so that the picking units made up of the rolls 21 and 22 will.

thus brush up and downwardly upon the plants, thereby insuring the collection of practically all of the cotton fiber upon the plants.

Obviously the reciprocation of the movable picking frames 17 and the units carried thereby will be set up by the shaft 61 and the parts connected thereto, driven by the worms 63 and gears 62 from the shaft 56 through belts 54. It is designed preferably to mount the frames 17 so that they will move in opposite directions simultaneously whereby each frame will counter balance the other and the power required for operating the two frames will thus be reduced to the minimum.

By referring to Figure 9 it will be noted that intersecting spiral grooves are formed in the picking roll and are indicated at 23'. The apertures pass through these grooves till incense at their points of intersection so that picking points {are thus provided where the grooves come to ether and these points constitute teeth which materially facilitate the picking operation.
